Unit-Economy

Since consciousness is a specific faculty, it has a specific nature or identity
and, therefore, its range is limited: it cannot perceive everything at once;
since awareness, on all its levels, requires an active process, it cannot do
everything at once. Whether the units with which one deals are percepts or
concepts, the range of what man can hold in the focus of his conscious
awareness at any given moment, is limited. The essence, therefore, of man’s
incomparable cognitive power is the ability to reduce a vast amount of
information to a minimal number of units—which is the task performed by his
conceptual faculty. And the principle of unit-economy is one of that
faculty’s essential guiding principles.

In any given moment, concepts enable man to hold in the focus of his conscious
awareness much more than his purely perceptual capacity would permit. The range
of man’s perceptual awareness—the number of percepts he can deal with at any
one time—is limited. He may be able to visualize four or five units—as, for
instance, five trees. He cannot visualize a hundred trees or a distance of ten
light-years. It is only his conceptual faculty that makes it possible for him
to deal with knowledge of that kind.

Conceptualization is a method of expanding man’s consciousness by reducing the
number of its content’s units—a systematic means to an unlimited integration
of cognitive data.

A concept substitutes one symbol (one word) for the enormity of the perceptual
aggregate of the concretes it subsumes. In order to perform its unit-reducing
function, the symbol has to become automatized in a man’s consciousness, i.e.,
the enormous sum of its referents must be instantly (implicitly) available to
his conscious mind whenever he uses that concept, without the need of
perceptual visualization or mental summarizing—in the same manner as the
concept “5” does not require that he visualize five sticks every time he uses
it.

For example, if a man has fully grasped the concept “justice,” he does not need
to recite to himself a long treatise on its meaning, while he listens to the
evidence in a court case. The mere sentence “I must be just” holds that meaning
in his mind automatically, and leaves his conscious attention free to grasp the
evidence and to evaluate it according to a complex set of principles. (And, in
case of doubt, the conscious recall of the precise meaning of “justice”
provides him with the guidelines he needs.)

It is the principle of unit-economy that necessitates the definition of
concepts in terms of essential characteristics. If, when in doubt, a man
recalls a concept’s definition, the essential characteristic(s) will give him
an instantaneous grasp of the concept’s meaning, i.e., of the nature of its
referents.
